FIRST
VARIABLE
LIFE INSURANCE COMPANY


August, 1998

Dear First Variable Contract Holder:

I am pleased to present the semi-annual report for the Variable Investors Series
Trust (VIST) and the Federated Prime Money Fund II. These portfolios are the
investments within your First Variable contract.

The stock market continued to perform well in the first half of 1998, with the
S&P 500 Index returning 17.70%. While the S&P 500 Index is one of the most
popular measures of market performance, it contains mainly larger-sized
companies. Concerns over the Asian turmoil helped drive funds into the larger
company stocks, which tend to be perceived as less risky than other types of
stocks.

As a result of this and other factors, the stocks of smaller companies, such as
those held by our Small Cap Growth Portfolio, did not perform as well during the
first two quarters. This pattern of different performance between various types
of stocks is not unusual. Sometimes one type of stock will be up, while another
will lag. By diversifying your portfolio among the different types of
investments offered within your First Variable contract, you can help protect
your investments from volatility in any single market sector.

Long-term interest rates fell during the first half of 1998, strengthening the
returns of fixed income securities. The bond market, as measured by the Salomon
Broad Investment Grade Bond Index, returned 4.17% during the first half of 1998.
High yield bonds continued to perform well and returned 4.31%, as measured by
the First Boston High Yield Index.

While the larger stocks have continued to show good returns, please remember
that a well diversified portfolio can help you better weather any type of
market. Ask your investment professional for more information on First
Variable's asset allocation models, which can form the basis of a solid
strategy.

Thank you for your continued business. We appreciate the opportunity to help you
build your wealth, enjoy the benefits of your efforts, and preserve your assets
for future generations.


                                    Sincerely,



                                    /s/ John M. Soukup

Small Cap Growth Portfolio                              
                                                        

Objective

Seeks capital appreciation by investing primarily in common stocks of emerging
companies with the potential for significant capital appreciation and strong
earnings growth with attendant risk. The Portfolio normally invests at least 65%
of assets in common stocks and convertible securities issued by companies with
market capitalization or annual revenues not exceeding $1 billion at the time of
purchase.

Management's Discussion & Analysis

Year to date, we have seen two very different periods. After a solid surge into
the end of 1997, the start to 1998 was a tepid one. Lower oil prices and
accounting issues in healthcare led to weakness in energy and physician practice
stocks causing January to start slowly. Strong earnings results helped turn the
quarter into a good one. As stated above, however, the environment turned
decidedly negative in the second period for reasons described.

While the year has been difficult so far, we expect the compelling small cap
valuation to be a primary driver in the near term. By several measures, small
cap stocks are at relative lows seen rarely in the last 40 years. In addition,
growth estimates for the S&P 500 are declining as economic growth is expected to
moderate while small cap growth expectations stocks continue strong. When
coupled with superior fundamentals, we feel investors will find it hard to
ignore the small cap arena.

The second quarter was impacted by the issues that have weighed heavily on 
investors' minds in recent periods. The Asian crisis reemerged and fears of 
inflation and higher interest rates continue to influence the financial 
markets. Small cap stocks were especially hurt by these factors. Investor 
preference for large, liquid investments also cast a pall on small cap 
stocks.

With an anemic April and poor May, another strong first quarter earnings period
was essentially overlooked in the face of these macroeconomics factors.
Fortunately, by the end of June, investors brightened at the prospects for the
second quarter.

Management's Discussion & Analysis (Continued)

In anticipation of the period, the structure of our portfolio has changed
somewhat. The impact of Asia on technology has lead to the sale of a number of
stocks with significant exposure to that region. As such, the funds have been
reinvested in companies more focused on domestic activities especially in the
service sector. While we do not make specific sector decisions, it is the
fundamentals of several companies in various subgroups of this sector that has
lead to an increased weighting in this area.

Consumer stocks posted positive returns in the quarter for the Small Cap Growth
Portfolio's Benchmark, the Russell 2000 Index. The Portfolio's general
underweighting relative to the Index and its heavier exposure to the lodging
subgroup caused this portion of the Portfolio to underperform. Also, holdings of
telecom equipment stocks were dramatically impacted by their concentrated
customer bases and foreign sales exposure causing negative relative results.

OUTLOOK

The current market environment is quite negative. Concerns over Asia and the
potential impact of wage inflation in the U.S. have cast a pall over the general
equity market. Technical indicators have also turned negative. When coupled with
a potential slowing in the economy, it becomes difficult to muster the courage
to invest. However, it is environments such as this that often create
significant opportunity for smaller stocks. When compared to larger stocks'
valuations and expectations, small cap stocks remain very attractive. A number
of studies illustrate that the opportunity for small cap outperformance from
current relative valuation levels is quiet high. As such, we fell that small cap
stocks are increasingly compelling. Further support can be found in second
quarter earnings results which indicate continued superior fundamental results
for small cap stocks. While the path to superior performance may not be smooth,
the earnings roadbed is solid. It is this base which we feel will lead to
improved performance.

"Total Return" is calculated including reinvestment of all income dividends and
capital gain distributions. Results represent past performance and do not
indicate future results. The value of an investment in the Small Cap Growth
Portfolio and the return on the investment both will fluctuate and redemption
proceeds may be higher or lower than an investor's original cost.

** Performance data is historical and includes changes in share price and
reinvestment of dividends and capital gains. Performance numbers are net of all
operating expenses, but do not include any insurance charges imposed in
connection with your variable insurance contract. If this performance
information included the effect of the insurance charges, performance numbers
would be lower.

Objective

The investment objective of the World Equity Portfolio is to seek maximum
long-term total return by investing primarily in common stocks, and securities
convertible into common stocks, traded in securities markets located around the
world, including the United States. This objective per First Variable's
instruction, is to be obtained via international "blue chips" and domestic U.S.
small cap stocks.

Management's Discussion & Analysis

INTERNATIONAL COMMENTARY

The first half of 1998 has seen very strong stock performance in the European
equity markets while the rest of the international equity universe have been
volatile and disappointing from a total return standpoint. Currently, twelve
developed foreign markets have U.S. dollar returns that exceed the +17.70%
return that investors have received from the S&P 500. All twelve of those
markets are European. European economies and markets continue to benefit from
low inflation, low relative interest rates, slow but improving growth, strong
bond markets, cost cutting, and corporate restructuring as the continent moves
toward the European Monetary Union in 1999. We currently have 51.3% of the
portfolio invested in Europe. The largest country weights in Europe and the
United Kingdom (17.8%), Switzerland (8.9%), and France (7.6%). We continue to be
the most optimistic about Europe.

Keys to performance have been our allocation in Europe and the performance of
our food, banking, pharmaceutical, publishing, and insurance stocks in this
market, and our ability to avoid the trouble spots in Japan, Asia, and Latin
America.

Currently, we have approximately 4.2% in Japan. We are monitoring Japan as their
financial system is restructured and the government attempts to improve their
domestic economy. We believe it will take Asia a long time to work through their
problems.

Additionally, the Portfolio has approximately 4% in the markets of Australia and
Canada. These markets were negatively impacted by the volatility

Management's Discussion & Analysis (Continued)

surrounding the Asian economies and markets that resurfaced in the second
quarter. However, our positions in these markets are primarily focused in the
financial and banking sectors of Canada and Australia. They performed relatively
well during this period of uncertainty as their domestic interest rates continue
to stay at relatively low levels, the prospects increase for possible
consolidation in these sectors, and the trend for bank managed 401k-like
investment programs continues to gain momentum.

The Portfolio benefited from our use of currency forwards to hedge against an
appreciating U.S. dollar. The U.S. dollar has strengthened versus the European
and Japanese currency year-to-date. Currently, the portfolio is 67% U.S. dollar
exposed. This figure takes into consideration our forward currency hedges, and
those countries whose currencies are linked to the U.S. dollar. Currencies that
we have partially hedged include the Australian dollar, Japanese yen, German
mark, Swiss franc, Dutch guilder, French franc, Swedish krona, and Spanish
peseta. On average these currencies declined - 3.2% versus the U.S. dollar
during the first half of the year. Currently 62% of the portfolio is invested in
international equities.

DOMESTIC COMMENTARY

The U.S. portion of the portfolio experienced a volatile quarter. The Russell
2000 Small Cap Index continued the strength of the first quarter until mid April
and then quickly declined 12%. The net result was a decline of 5% for the
quarter. The portfolio performed at a slightly better level. Strength came from
several areas of high technology. Such as stocks as Lycos, in internet services,
Exodus in network communications, Antec in Cable TV set top boxes, and Computer
Leaning Centers in education all provided gains of 40% or more during the
quarter. Overall results were tempered by weakness in energy related stocks. The
consensus outlook has been one of greater concern for Asian economies to slow
earnings growth in the U.S. We feel that there are several areas for small cap
investment where this is not a concern. Small U.S. stocks are reaching very
attractive valuations. The long-term outlook remains positive. Currently, 35% of
the portfolio is invested in domestic small-cap stocks.

PERFORMANCE

The year-to-date performance of the World Equity Portfolio is 15.9%. The MSCI
World Index is 16.9%. For the second quarter the Fund was .97% versus 2.1% for
the index.

Objective

Seeks capital growth by investing primarily in common stocks and securities
convertible into common stock. Also seeks current income when consistent with
the primary objective. Securities are selected on the basis of their issuers'
long-term potential for expanding their earnings, profitability, and size and on
the basis of potential increases in market recognition of their securities.

Management's Discussion & Analysis

The stock market posted strong returns in the first half of 1998, with the S&P
500 up 17.7%. Despite grave concerns about the impact of Southeast Asian
currency devaluations on the U.S. economy at the end of 1997, a favorable
economic environment prevailed. This was characterized by stronger-than
anticipated and likely unsustainably-high GDP growth in the first quarter and
moderate inflation. Long-term interest rates dropped significantly, from 5.9% at
the end of March to 5.6% at the end of June. The S&P 500 rebounded sharply in
the first quarter, up 14.0%. However, fears about the Pac Rim and Japan, in
particular, resurfaced in the second quarter. The market focus was clearly
liquidity oriented, with money flowing into large-cap stocks to the detriment of
their small-cap brethren. In the June quarter, the S&P 500 return of 3.3% w as
significantly lower than that of the first quarter. Given the deflationary
implications of the situation in Southeast Asia and the lack of significant
evidence of runaway inflation, the Federal Reserve Board did not raise
short-term interest rates. We do not foresee any change in monetary policy as
the second half of the year unfolds.

First-quarter GDP growth of 5.4% was rather robust, and will probably decelerate
over the remainder of the year, to a range of 2.0-2.5%. This reflects the impact
of the General Motors strike, the strength of the dollar, the weakness in
Southeast Asia, and the likelihood that the inventory overhang from the first
quarter will be worked down. We expect inflation to remain moderate, with both
the CPI and PPI in the 1%-2% range. The weakness in the Pac Rim economies will
likely have an impact on U.S. corporate profit growth.

Management's Discussion & Analysis (Continued)

PERFORMANCE

The Growth Portfolio had a total return (including dividends and income) for the
second quarter of 1998 of 4.39% as compare to 3.30% for the Standard & Poor's
500 Index. Stock selection is guided by the Value Line Timeliness Ranking
System, which focuses on stocks with superior earnings growth and price
momentum. In the second quarter, the Portfolio benefited from strong performance
in the retail sector, finance, and technology, but was hurt by holdings in
energy, transportation and housing.

OUTLOOK

We believe that the U.S. economy, with moderating GDP growth, benign inflation
and relatively stable interest rates, provides a favorable backdrop for the
equity market. However, given the strong performance of the market through the
first half, we remain somewhat cautious over the remainder of the year. Although
the market shrugged off the implications of the Southeast Asian currency
devaluations in the first quarter, there are still risks associated with this
part of the world. And the very significant problems in the Japanese economy
represent yet another unknown. Second-quarter earnings reports should begin to
provide some insight on these issues. Nonetheless, our investment discipline
leads us to companies that continue to exhibit attractive growth rates within a
broad array of industry sectors, which should position the portfolio well going
forward. Our largest sector weightings are technology, finance, healthcare and
consumer cyclicals.

Objective

Seeks capital appreciation and current income by investing in a diversified
portfolio of equity securities that is selected on the basis of a proprietary
analytical model.

Management's Discussion & Analysis

U.S. equity market returns were dampened from the swift pace earlier in 1998, as
demonstrated by the 3.3% return for the S&P 500 Index over the second quarter.
While this return seems weak by recent standards, the market shrugged off a
mini-correction and continuing Asian economic turmoil, and has pushed the
large-cap U.S. stock indices back to new records. This Index return equates to
an annual return of nearly 14%, strong on an historical absolute basis. With
many economies virtually collapsing around the pacific rim, U.S. corporate
profits slowing, and signs of decelerating economic growth around the world, the
resilience of the U.S. stock market continues to surprise most investors.
Additionally, the consumer-led front end of the economy continues to be strong.
Despite slower earnings for companies in the S&P 500 over the second quarter,
S&P 500 dividends continued to accelerate. While cyclicals such as capital goods
(-2.1%) and basic materials (-3.8%) lagged the Index returns for the quarter,
technology (+9.6%), health care (+6.5%), financials (+4.7%), and utilities
(+3.7%) lead Index returns. On an individual stock basis, the largest of the
best known blue chips continue to carry returns for the S&P 500. Investors
seeking out the largest and best-know n names and increased risk-aversion as the
economy begins to slow, may be reasons for the continued strength among the
largest of the large caps.

PERFORMANCE

In this dampened equity environment, the Matrix Equity Portfolio returned 14.96%
for the first half of 1998. At the sector level, the Portfolio was overweight
relative to the Index in technology, consumer cyclicals, and capital goods. We
held slight overweight positions in health care and communication services. We
held significant underweight S&P 500 benchmark-relative positions in consumer
staples, while we were slightly underweight the benchmark in basic materials,
energy, transportation and utilities. On the good news front, the Portfolio was
helped by our technology weighting in tech manufacturing, and

Management's Discussion & Analysis (Continued)

our sector exposure to financials, the brokerage firms in particular. On the bad
news front, the Portfolio was hurt relative to the benchmark in communication
services, the telephones specifically. The Portfolio was also hindered due to
stock selection in defense/aerospace and industrial services.

Our investment process emphasizes quantitative modeling, which implements an
integrated growth and value bottom-up stock selection method designed to
outperform the Index over the long-term. While risk controls are used in
portfolio construction, we will take active bets away from the benchmark in
those industries where we see fair valuations and strong long-term growth
prospects. Because value is an integral component of the investment process, the
Portfolio will not be overweighted in excessively expensive stocks. Our
disciplined approach hurt Portfolio returns in industries where price momentum
continues in unhesitating fashion.

RESEARCH UPDATE: INDUSTRY CLUSTER ANALYSIS

The U.S. Active Equity team is always searching for ways to improve the
return/risk profile of our strategies. There are two ways to accomplish this:
generate more excess return or enhance risk controls without compromising excess
return.

Within our Value Model, we assess companies on an industry relative basis in
order to identify the best and worst companies within a particular industry. Our
approach is more effective in industries with greater numbers of companies
because, in general, there is more of a difference between the "best" and
"worst" companies within that industry. Recognizing this issue led us to the
concept of "industry clusters."

Initially, we believed that if we grouped industries exhibiting similar
characteristics together, our differentiation power would improve our
proprietary model's stock ranking process. The first step in the process of
testing this hypothesis involved determining the industry clusters. SSgA's
Advanced Research Center assisted with the initial review. We performed returns
based statistical analysis including a price-to-book factor that resulted in 30
industry clusters.

Overall the preliminary review resulted in intuitively logical groupings: there
were also some unusual results such as a cluster of Retail Food, Apparel and
Publishing. The U.S. Active Equity Team reviewed the cluster groups to make sure
the industries within the cluster were driven by the same macroeconomic factors.
For example, Railroads, Freight, Airlines and Trucking were grouped together
because they are influenced by commerce and fuel prices. Ultimately, 24 industry
clusters were agreed on from both a statistical and intuitive perspective.

Backtesting was the next step toward implementation of the industry clusters. We
looked at our base case versus simulations using conservative transaction costs.
We also monitored turnover to insure that in "real life," the strategy would not
experience a change in the level of portfolio turnover.

The results were favorable using 24 industry clusters instead of the 53 BARRA
industries improves the power of our Value Model and improves portfolio returns
with a modest increase in overall portfolio risk. We plan to implement this
enhancement later this July. April 1, 1994 results were achieved by different
portfolio managers.

                                                        [LOGO]

Objective

Seeks long-term growth of capital and income and a reasonable current return by
investing primarily in dividend-paying common stocks, convertibles, and readily
marketable securities that derive their value from common stocks, as well as
fixed income securities. The Portfolio does not strive to maintain a specific
balance of stocks, bonds, and money market instruments. Instead the manager
selects the industry sectors and individual securities he believes have the
highest potential for attractive total returns.

Management's Discussion & Analysis

The U.S. stock market as a whole had strong performance over the
January-through-June period. Asia-related earnings uncertainties
notwithstanding, investor sentiment toward equities remained favorable through
the period, supported by a continued healthy economy and subdued inflation. The
Portfolio benefited from this positive sentiment, and from strong showings from
its financial, telecommunications and aerospace holdings in particular. Stocks
that hampered the Portfolio's return included its energy and tobacco-related
holdings, which lagged the broader market during the period.

PERFORMANCE

For the six months ended June 30, 1998, the Portfolio had a gain of 12.71% vs.
gains of 17.70% for the S&P 500 Index* and 12.11% for the Lipper Growth & Income
Funds Index.**

PORTFOLIO CHANGES

We made few noteworthy changes to the Portfolio's industry exposure during the
first six months of 1998. It remained broadly diversified by sector, finding
little incentive, from a relative-valuation perspective, to heavily overweight
specific areas. That said, we continued to select stocks strictly on a bottom-up
basis, emphasizing companies with good cash-flow generation and potential for
significant earnings growth.

The Portfolio's noteworthy areas of concentration included the financial
services industry, a weighting which was increased over the course of the
period. We identified several attractive buying opportunities here during the
first six months, holding a mix of insurance, asset-management and
mortgage-services companies. Elsewhere in the financial industry, we maintained
a limited exposure to banking stocks, since we viewed most as expensive. That
said, we found several issues that we deemed

Management's Discussion & Analysis (Continued)

to be attractively priced, including First Chicago NBD, which we purchased in
the wake of its announced merger with Banc One Corp. In our view, the synergies
created by the merger are significant and should support the stock's long-term
performance.

We also maintained a modestly overweighted position in the energy sector, with
the focus here remaining on efficiently managed oil exploration and production
companies with expanding capacity profiles, which we believe have good
longer-term prospects. One name added was Occidental Petroleum, a stock found
attractive for its significant dividend yield and, given the company's recent
restructuring announcements, long-term appreciation potential.

Within the health-care sector, we continued to emphasize managed-care companies
with good enrollment growth and a firm hand on costs. One stock added was United
Healthcare, an HMO whose longer-term prospects we view favorably due in part to
the company's recent strategic acquisitions.

The Portfolio also continued to have a sizable exposure to consumer-type stocks,
including a significant weighting in the consumer durables sector where one of
the Portfolio's largest position throughout the period was Chrysler. In other
consumer-related areas, we continued to have a significant weighting in the
retail sector. We made a few adjustments here during the first six months of
1998, most notably establishing a position in Sears Roebuck and reducing then
eliminating the position in Wal-Mart, on profit-taking.

The balance of the Portfolio remained invested across a broad range of
industries, including technology, where we generally found the best
risk-adjusted growth prospects in the computer sector.

OUTLOOK

Looking ahead to the next several months, we believe the stock market will
continue to be characterized by generally lofty equity valuations and
considerable volatility. Set within this environment, we continue to place a
premium on risk management for the portfolio as a whole. As a result, individual
stock selection remains critical, and we will continue to hold only those stocks
we deems have the best longer-term risk-adjusted performance potential.

Objective

Seeks as high a level of total return over an extended period of time as is
consistent with prudent investment risk by investing in equity securities, bonds
and money market instruments in varying proportions, depending upon prevailing
economic and financial market conditions.

Management's Discussion & Analysis

The Portfolio had a total return of 4.14% for the quarter, compared to 3.03% for
a 60% S&P 500/40% Lehman Government Corporate Bond Index composite. On June 30,
1998, the Portfolio was 77.3% invested in common stocks, 18.8% in bonds with a
mixture of high grade corporates, government, and government agencies, and
approximately 3.9% in short-term securities. No changes in the asset class
weightings have been made since the first quarter. The overweighting in equities
vis-a-vis the benchmark contributed to the outperformance. The equity portion of
the portfolio was up 4.91%, outpacing the S&P 500 return of 3.30%. The fixed
income portion of the portfolio benefited from the rally in the bond market and
gained 2.66%, modestly beating the Lehman Government Corporate Bond Index return
of 2.62%.

The equity holdings in the Portfolio mirror those of the Growth Portfolio and
will continue to do so. Selection is guided by the Value Line Timeliness Ranking
System, which favorably ranks stocks with earnings and price momentum. Our
heaviest section weightings are in technology, finance, healthcare and consumer
cyclicals, sectors that are relatively more attractive in terms of
above-trendline growth patterns.

Objective

Seeks a high level of current income while secondarily seeking capital
appreciation by investing primarily in fixed-income securities, including
corporate bonds and notes, discount bonds, zero-coupon bonds, convertible
securities, and preferred stocks and bonds issued with warrants, which are rated
Baa or below by Moody's or BBB or below by Standard & Poor's or in unrated
securities determined to be of comparable quality.

Management's Discussion & Analysis

Two opposing factors impacted the high yield market during the six months ended
June 30, 1998. On the positive side, the domestic economy continued to generate
strong growth. On the negative side, Asian economies continued to struggle. In
the early part of the period, the strong domestic economy held the upper hand.
However, late in the second quarter, Asian economic problems and their impact on
the domestic economy became a key investor focal point. Economic statistics
seemed to indicate that domestic economic growth was slowing with imports
increasing, exports decreasing, inventories accumulating, and manufacturing
activity slowing. This apparent slowing of the domestic economy caused the
spread between high yield bonds and treasuries to widen approximately 40 basis
points and high quality bonds to outperform high yield bonds in the second
quarter. However, strong first quarter performance for high yield bonds allowed
them to outperform high quality bonds for the six month period. For example, the
Lehman Brothers High Yield Bond Index returned 4.5% for the six months versus
3.94% for the Lehman Brothers Aggregate Bond Index, a measure of high quality
bond performance.

PERFORMANCE

The Portfolio (which returned 4.21%) modestly underperformed the First Boston
High Yield Bond Index (which returned 4.31%) while outperforming the Lehman
Brothers High Yield Bond Index (on a gross basis) during the period.

Management's Discussion & Analysis (Continued)

Several factors impacted performance during the period. The portfolio is
overweight in the broadcast radio and TV sector which generated outstanding
returns led by companies such as Chancellor Media and Sinclair Broadcasting. The
portfolio's cable TV positions outperformed driven by consolidation activity in
the United Kingdom and AT&T's acquisition of Telecommunication, Inc. in the U.S.
which reinforced the attractiveness of the cable platform. The portfolio also
benefited by the strong performance of several specific holdings including
Nextel, Echostar, Six Flags and Dialog Corp. The energy sector was one of the
worst performing sectors in the market due to falling oil prices. The portfolio
had several holdings which underperformed the overall market but the fund did
benefit by being underweight in the sector. On the negative side, the
portfolio's large holdings in telecommunications issues suffered late in the
period given a combination of an uncertain market and the step-up nature of many
of the portfolio's telecommunication holdings. The portfolio was also negatively
impacted by its holdings in Renaissance Cosmetics (subsequently sold), Icon
Health and Fitness, Electronic Retailing and Highwaymaster which underperformed
the overall market based on disappointing financial performance.

OUTLOOK

The performance of the high yield market over the balance of 1998 will be a
function of the domestic economy and the strength of corporate profits. We
believe that the domestic economy is slowing and corporate profits may
disappoint optimistic expectations. Demand in Asia is weak while supply from
that region in industries such as semiconductors and steel is impacting domestic
companies. From a high yield perspective, this weakness could lead to additional
spread widening. However, we believe that the economy will not sink into
recession and additional spread widening should be modest given the approximate
125 basis point widening since early October, 1997. Also the lull in the economy
in the second half of 1998 may set the stage for a continuation of the current
business cycle into 1999 and beyond resulting in subsequent spread tightening.

The portfolio remains overweight in the telecommunication, cable TV and
broadcasting sectors given our belief that secular changes occurring in these
industries will make them superior performers over the next six to twelve
months. We also believe these sectors will outperform in a slowing economic
environment. We are maintaining a bias toward high quality high yield bonds in
light of potential spread widening although we are beginning to look for
attractive opportunities in lower rated bonds given the spread widening to date.

Objective

Seeks current income and preservation of capital. Under normal circumstances, at
least 80% of the Portfolio's assets will be invested in U.S. Government
Securities; the remainder may be invested in investment grade corporate
securities and in cash and money market instruments.

Management's Discussion & Analysis

Amid renewed concerns about the global deflationary impact of the financial and
economic crisis in Asia, bond market yields declined in the second quarter. A
fairly dramatic drop of 30 basis points occurred in the long maturities,
compared with little change on the short end, producing a pronounced flattening
in the yield curve.

Adjusted for duration differences, U.S. Treasury securities rose more in price
than either corporate or mortgage bonds. Yield spreads over Treasuries in many
corporate sectors rose to their widest levels in five years amid heavy new
issuance. Asian-related credits came under renewed pressure as fears were
reinforced by news of the deteriorating conditions there. Meanwhile,
mortgage-backed issues suffered from accelerating refinancing activity, which
pushed managers to move into longer Treasuries to maintain the duration of their
portfolios. In the high-yield market, prices actually declined on balance during
the period.

PERFORMANCE

For the quarter, the Salomon Broad Investment Grade bond index returned a strong
2.1% while the average U.S. bond mutual fund gained 1.6%.

The U.S. Government Bond Fund performed in line with its benchmark in the second
quarter. We upgraded the overall credit quality of the portfolio at the
beginning of the quarter by reducing our allocation to corporate bonds. This
change helped performance as corporate bonds generally underperformed Treasury
securities in the period.

Management's Discussion & Analysis (Continued)

In addition, our mortgage-backed securities performed significantly better than
mortgages in general, primarily because our mortgage-backed portfolio has better
call-protection than the overall mortgage sector. Finally, we were vigilant
about adding duration to the portfolio as interest rates declined and the
duration of the market index lengthened.

OUTLOOK

We anticipate that the current environment of reasonably stable interest rates
will continue. Inflation will remain stable and while the recent torrid growth
rate of the U.S. economy is likely to slow, it will not warrant policy action by
the Federal Reserve. We anticipate maintaining duration at or slightly above
benchmark. While we remain optimistic about the U.S. economy, we are taking
advantage of easy opportunities to improve credit quality and liquidity with
minimal give-up in yield.

                         VARIABLE INVESTORS SERIES TRUST
                          NOTES TO FINANCIAL STATEMENTS
                            June 30, 1998 (Unaudited)


NOTE A -- ORGANIZATION

      Variable Investors Series Trust (the "Trust") was established as a
Massachusetts business trust under the laws of Massachusetts by an Agreement and
Declaration of Trust dated December 23, 1986. The Trust is an open-end, series
management investment company which currently comprises eight series of shares
of beneficial interest (the "Portfolios") each of which represents the entire
interest in a separate portfolio of investments. The Portfolios are the Small
Cap Growth Portfolio, the World Equity Portfolio, the Growth Portfolio, the
Matrix Equity Portfolio, the Growth & Income Portfolio, the Multiple Strategies
Portfolio, the High Income Bond Portfolio, and the U.S. Government Bond
Portfolio.


NOTE B -- SIGNIFICANT ACCOUNTING POLICIES

      The following is a summary of significant accounting policies followed by
the Trust in the preparation of its financial statements.

      ESTIMATES: The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

      VALUATION OF INVESTMENTS: The Trust's equity securities, including
American Depositary Receipts (ADR's) and other forms of depository receipts,
traded on a national securities exchange are valued at the last sales price, or,
if no closing price is available, at a bid price estimated by a broker or
dealer. Debt securities are generally valued on the basis of valuations
furnished by pricing services which determine valuations for normal
institutional size trading units of debt securities, without exclusive reliance
upon quoted prices. These valuations are believed to reflect with greater
accuracy the fair market value of such securities. Short-term securities
maturing in 60 days or less are valued at cost plus earned discount to maturity
(amortized cost), which approximates market value. Securities in other mutual
funds are valued at the net asset value of those funds. Securities for which
current market quotations are not readily available are stated at fair value as
determined in good faith under the direction of the Trustees.

      FOREIGN SECURITIES: Foreign securities traded on a recognized securities
exchange are valued at the last sales price in the principal market where they
are traded, or, if closing prices are unavailable, at the last bid price
available prior to the time a Portfolio's net asset value is determined. Foreign
portfolio security prices are furnished by quotation services expressed in the
local currency's value and are translated into U.S. dollars at the current rate
of exchange. Foreign securities for which prices cannot be obtained by the
quotation services are valued using dealer supplied quotations.


      REPURCHASE AGREEMENTS: In connection with transactions in repurchase
agreements, the Trust's custodian takes possession of the underlying collateral
securities, the value of which at least equals the principal amount, including
interest, of the repurchase transaction. To the extent that any repurchase
transaction exceeds one business day, the value of the collateral is
marked-to-market on a daily basis to ensure the adequacy of the collateral. In
the event of default of the obligation to repurchase, the Portfolio has the
right to liquidate the collateral and apply the proceeds in satisfaction of the
obligation. Under certain circumstances, in the event of default or bankruptcy
by the other party to the agreement, realization and/or retention of the
collateral, or proceeds may be subject to legal proceedings.

                         VARIABLE INVESTORS SERIES TRUST
                          NOTES TO FINANCIAL STATEMENTS
                            June 30, 1998 (Unaudited)
                                   -CONTINUED-

      INVESTMENT TRANSACTIONS: Investment security transactions are recorded on
the date of purchase, sale, or maturity. Dividend income is recorded on the
ex-dividend date, or, in the case of dividend income on foreign securities, on
the ex-dividend date or when the Trust becomes aware of its declaration.
Interest income is recorded on the accrual basis. Realized gains and losses from
security transactions are determined on the basis of identified cost.

      FOREIGN CURRENCY TRANSLATIONS: The records of the Trust are maintained in
U.S. dollars. Foreign currency amounts are translated into U.S. dollars at a
current rate of exchange of such currency to determine the value of investments,
other assets and liabilities on the date of any determination of net asset value
of the Portfolios. Purchases and sales of securities and income and expenses are
converted at the prevailing rate of exchange on the respective dates of such
transactions. Net realized gain (loss) on foreign currency includes net realized
currency gains and losses recognized between accrual and payment dates. The
Portfolios do not isolate that portion of the results of operations resulting
from changes in foreign exchange rates on investments from fluctuations arising
from changes in market prices of securities held. Such fluctuations are included
with the net realized and unrealized gain or loss from investments.

      FORWARD FOREIGN CURRENCY CONTRACTS: Upon the purchase or sale of a
security denominated in foreign currency, the Trust may enter into a forward
currency exchange contract for the purchase or sale, for a fixed amount of U.S.
dollars, of an amount of the foreign currency required to settle the security
transaction in order to hedge against a change in the foreign currency exchange
rate. Accordingly, the Trust would not realize currency gains or losses between
the trade and settlement dates on such security transactions. A Portfolio may
engage in position hedging to protect against a decline in value relative to the
U.S. dollar of the currencies in which their portfolio securities are
denominated or quoted.

      The net U.S. dollar value of foreign currency underlying all contractual
commitments held by the Trust on each day and the resulting net unrealized
appreciation (depreciation) and related net receivable (payable) amount are
determined by using foreign currency exchange rates supplied by a quotation
service.

      Realized gain (loss) includes net gains or losses realized by the Trust on
contracts which have matured or which the Trust has terminated by entering into
an offsetting closing transaction.

      FORWARD COMMITMENTS: To secure prices or yields deemed advantageous at a
particular time, each Portfolio of the Trust may enter into a forward commitment
in which a Portfolio agrees on trade date to either make or receive delivery
against payment for securities on a delayed delivery basis. The price and
interest rate of such securities are fixed at trade date. For forward commitment
purchases, the Portfolio does not earn interest on such security until
settlement date.

      FEDERAL INCOME TAXES: Each Portfolio of the Trust is treated as a separate
entity for Federal tax purposes. Each Portfolio of the Trust has qualified and
intends to continue to qualify each year as a "regulated investment company"
under Subchapter M of the Internal Revenue Code, as amended. By so qualifying,
the Portfolios of the Trust will not be subject to Federal income taxes to the
extent that they distribute all of their taxable income, including realized
capital gains, for the fiscal year. In addition, by distributing during each
calendar year substantially all of their net investment income, capital gains
and certain other amounts, if any, the Portfolios of the Trust will not be
subject to a Federal excise tax.

      As of December 31, 1997, the High Income Bond Portfolio had a realized
capital loss carryforward, for Federal income tax purposes, of $384,526
($291,888 expires on December 31, 2002, $52,592 expires on December 31, 2003,
and $40,046 expires on December 31, 2005), available to be used to offset future
realized capital gains.

      EXPENSES: Expenses directly attributable to a Portfolio are charged to

evenly among the affected Portfolios, allocated on the basis of relative average
net assets, or otherwise allocated among the Portfolios as the Trustees may

      DIVIDENDS AND DISTRIBUTIONS: Each of the Portfolios declares and
distributes dividends from net investment income, if any, and distributes its
net realized capital gains, if any, at least annually. Income and capital gain
distributions are determined in accordance with income tax regulations which may
differ from generally accepted accounting principles.

      These differences are primarily due to utilization of capital loss
carryovers, differing treatments for foreign currency transactions and
differences in the timing of recognition of certain capital losses for financial
reporting and tax purposes. Both dividends and capital gain distributions are
made in shares of such Portfolios unless an election is made on behalf of an
Separate Account to receive dividends and capital gain distributions in cash.

annual rate of 0.50% of a Portfolio's average daily net assets (0.25% in the
case of the U.S. Government Bond Portfolio).

NOTE F -- YEAR 2000 ISSUE

     Like other mutual funds, as well as other financial and business
organizations around the world, the Trust could be adversely affected if the
computer systems used by the Adviser, the Sub-Adviser and other service
providers, in performing their administrative functions do not properly process
and calculate date-related information and data as of and after January 1,
2000. This is commonly known as the "Year 2000 Issue." The Adviser and
Sub-Advisers are taking steps that they believe are reasonably designed to
address the Year 2000 Issue with respect to computer systems that they use and
to obtain reasonable assurances that comparable steps are being taken by the
Trust's other major service providers. At this time, however, there can be no
assurance that these steps will be sufficient to avoid any adverse impact to the
Trust.

                              PRESIDENT'S MESSAGE

- --------------------------------------------------------------------------------

Dear Shareholder:

I'm pleased to present your Semi-Annual Report to Shareholders for Federated
Prime Money Fund II, a portfolio of Federated Insurance Series.

The Report covers the six-month reporting period from January 1, 1998 through
June 30, 1998. It begins with an investment review by the fund's portfolio
manager, which is followed by a complete listing of the fund's holdings and its
financial statements.

This high-quality money market fund keeps your ready cash pursuing daily income
while keeping your principal stable.* And, you have convenient, daily access to
your money.

To help provide a competitive daily yield, the fund invests in a diversified
portfolio of high-quality money market securities. At the end of the six-month
reporting period, the portfolio was invested in repurchase agreements (32.5%),
commercial paper (29.3%), variable rate notes (20.0%), short-term notes (9.7%),
and certificates of deposit (8.4%).

During the six-month reporting period, the fund paid a total of $0.02 per share

                               INVESTMENT REVIEW
- --------------------------------------------------------------------------------

Federated Prime Money Fund II (the "Fund") invests in money market instruments
maturing in 397 days or less. The average maturity of these securities, computed
on a dollar weighted basis, is restricted to 90 days or less. Portfolio
securities must be rated in one of the two highest short-term rating categories
by one or more of the nationally recognized statistical rating organizations or
be of comparable quality to securities having such ratings. Typical security
types include, but are not limited to, commercial paper, certificates of
deposit, time deposits, variable rate instruments and repurchase agreements.

During the first half of 1998, inflation remained subdued although inflationary
pressures were building. The strength in domestic consumer spending and housing
was offset by the turbulence in many Asian economies and a domestic inventory
overhang as imports to the U.S. exceeded exports. Monetary policy remained on
hold throughout the first half of 1998 due to the continued problems in Asia,
despite strong domestic economic growth. Nevertheless, the Federal Reserve Board
(the "Fed") maintained a bias toward tightening due to strong domestic growth,
tight labor markets and rapidly rising labor costs. The dampening inflationary
effects of the emerging markets and domestic inventory adjustments could prove
to be temporary and inflationary pressures could rise.

Market interest rates should remain in a narrow trading range throughout the
second half of 1998. The 30-day commercial paper rate began 1998 at a high of
5.56% and traded as low as 5.43% on January 22, 1998. Thirty-day commercial
paper has traded around the federal funds target rate of 5.50% throughout the
first half of 1998. Ninety-day commercial paper rates have also traded within
this range as the yield curve remains extremely flat.

The target average maturity range for the Fund remained in the 35-45 day target
range for the entire period, reflecting a neutral position regarding Fed policy.
In structuring the Fund, there is continued emphasis placed on positioning
30-35% of the Fund's core assets in variable rate demand notes and accomplishing
a modest barbell structure.

During the six months ended June 30, 1998, the net assets of the Fund increased
from $59.7 to $78.3 million while the 7-day net yield decreased from 5.10% to
4.94%.* The effective average maturity of the Fund on June 30, was 44 days.



*    Performance quoted represents past performance and is not indicative of
     future results. Yield will vary. Yields quoted for money market funds most
     closely reflect the fund's current earnings. Performance information does
     not reflect the charges and expenses of a variable annuity or variable life
     insurance contract.

                          NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------
                          FEDERATED PRIME MONEY FUND II
                            JUNE 30, 1998 (UNAUDITED)

ORGANIZATION
Federated Insurance Series (the "Trust") is registered under the Investment
Company Act of 1940, as amended (the "Act") as an open-end, management
investment company. The Trust consists of eight portfolios. The financial
statements included herein are only those of Federated Prime Money Fund II (the
"Fund"), a diversified portfolio. The financial statements of the other
portfolios are presented separately. The assets of each portfolio are segregated
and a shareholder's interest is limited to the portfolio in which shares are
held. The investment objective of the Fund is to provide current income
consistent with stability of principal and liquidity. 


SIGNIFICANT ACCOUNTING POLICIES. 
The following is a summary of significant accounting policies consistently
followed by the Fund in the preparation of its financial statements. These
policies are in conformity with generally accepted accounting principles.

INVESTMENT VALUATIONS
The Fund uses the amortized cost method to value its portfolio securities in
accordance with Rule 2a-7 under the Act.

REPURCHASE AGREEMENTS
It is the policy of the Fund to require the custodian bank to take possession,
to have legally segregated in the Federal Reserve Book Entry System, or to have
segregated within the custodian bank's vault, all securities held as collateral
under repurchase agreement transactions. Additionally, procedures have been
established by the Fund to monitor, on a daily basis, the market value of each
repurchase agreement's collateral to ensure that the value of collateral at
least equals the repurchase price to be paid under the repurchase agreement
transaction.

The Fund will only enter into repurchase agreements with banks and other
recognized financial institutions, such as broker/dealers, which are deemed by
the Fund's adviser to be creditworthy pursuant to the guidelines and/or
standards reviewed or established by the Board of Trustees (the "Trustees").
Risks may arise from the potential inability of counterparties to honor the
terms of the repurchase agreement. Accordingly, the Fund could receive less than
the repurchase price on the sale of collateral securities.

INVESTMENT INCOME, EXPENSES AND DISTRIBUTIONS
Interest income and expenses are accrued daily. Bond premium and discount, if
applicable, are amortized as required by the Internal Revenue Code, as amended
(the "Code"). Distributions to shareholders are recorded on the ex-dividend
date.

FEDERAL TAXES
It is the Fund's policy to comply with the provisions of the Code applicable to
regulated investment companies and to distribute to shareholders each year
substantially all of its income. Accordingly, no provisions for federal tax are
necessary.

WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS
The Fund may engage in when-issued or delayed delivery transactions. The Fund
records when-issued securities on the trade date and maintains security
positions such that sufficient liquid assets will be available to make payment
for the securities purchased. Securities purchased on a when-issued or delayed
delivery basis are marked to market daily and begin earning interest on the
settlement date.

RESTRICTED SECURITIES
Restricted securities are securities that may only be resold upon registration
under federal securities laws or in transactions exempt from such registration.
Many restricted securities may be resold in the secondary market in transactions
exempt from registration. In some cases, the restricted securities may be resold
without registration upon exercise of a demand feature. Such restricted
securities may be determined to be liquid under criteria established by the
Trustees. The Fund will not incur any registration costs upon such resales.
Restricted securities are valued at amortized cost in accordance with Rule 2a-7
under the Act.

Additional information on the restricted securities held at June 30, 1998 are as
follows:

USE OF ESTIMATES

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the amounts of assets, liabilities, expenses and revenues reported in the
financial statements. Actual results could differ from those estimated.

OTHER
Investment transactions are accounted for on the trade date.

SHARES OF BENEFICIAL INTEREST
The Declaration of Trust permits the Trustees to issue an unlimited number of
full and fractional shares of beneficial interest (with-out par value). At June
30, 1998, capital paid-in aggregated $78,267,173.

Transactions in shares were as follows:

INVESTMENT ADVISORY FEE AND OTHER TRANSACTIONS WITH AFFILIATES
INVESTMENT ADVISORY FEE
Federated Advisers, the Fund's investment adviser (the "Adviser"), receives for
its services an annual investment advisory fee equal to 0.50% of the Fund's
average daily net assets. The Adviser may voluntarily choose to waive any
portion of its fee. The Adviser can modify or terminate this voluntary waiver at
any time at its sole discretion.

ADMINISTRATIVE FEE
Federated Services Company ("FServ"), under the Administrative Services
Agreement, provides the Fund with administrative personnel and services. The fee
paid to FServ is based on the level of average aggregate daily net assets of all
funds advised by subsidiaries of Federated Investors, Inc. for the period. The
administrative fee received during the period of the Administrative Services
Agreement shall be at least $125,000 per portfolio and $30,000 per each
additional class of shares.

TRANSFER AND DIVIDEND DISBURSING AGENT FEES AND EXPENSES
FServ, through its subsidiary, Federated Shareholder Services Company ("FSSC")
serves as transfer and dividend disbursing agent for the Fund. The fee paid to
FSSC is based on the size, type, and number of accounts and transactions made by
shareholders.

ORGANIZATIONAL EXPENSES
Organizational expenses of $22,431 were borne initially by the Adviser. The Fund
has reimbursed the Adviser for these expenses. These expenses have been deferred
and are being amortized over the five-year period following the Fund's effective
date. For the period ended June 30, 1998, the Fund was fully amortized.

PORTFOLIO ACCOUNTING FEES
FServ maintains the Fund's accounting records for which it receives a fee. The
fee is based on the level of the Fund's average daily net assets for the period,
plus out-of-pocket expenses.

GENERAL
Certain of the Officers and Trustees of the Trust are Officers and Directors or
Trustees of the above companies.

YEAR 2000
Similar to other financial organizations, the Fund could be adversely affected
if the computer systems used by the Fund's service providers do not properly
process and calculate date-related information and data from and after January
1, 2000. The Fund's Adviser and Administrator are taking measures that they
believe are reasonably designed to address the Year 2000 issue with respect to
computer systems that they use and to obtain reasonable assurances that
comparable steps are being taken by each of the Fund's other service providers.
At this time, however, there can be no assurance that these steps will be
sufficient to avoid any adverse impact to the Fund.

Variable funds are not bank deposits or obligations, are not guaranteed by any
bank, and are not insured or guaranteed by the U.S. government, the Federal
Deposit Insurance Corporation, the Federal Reserve Board, or any other
government agency. Investment in variable funds involves investment risk,
including the possible loss of principal. Although money market funds seek to
maintain a stable net asset value of $1.00 per share, there is no assurance that
they will be able to do so.

This report is authorized for distribution to prospective investors only when
preceded or accompanied by the fund's prospectus, which contains facts
concerning its objective and policies, management fees, expenses, and other
information.

ASSET ALLOCATION STRATEGIES

Asset Allocation is dividing your portfolio among several different investment
categories, such as stocks, bonds and money market instruments. Asset allocation
theory helps you and your investment professional design a portfolio that meets
your tolerance for risk. It can also help you gain the most potential return for
a certain risk level. First Variable Life offers a menu of asset allocation
models that can help you build, enjoy and preserve your wealth.

AUTOMATIC ASSET REBALANCING

Once you and your investment professional have selected a mix of investments,
automatic asset rebalancing helps you maintain it by rebalancing your portfolio.
Choose from quarterly, semi-annual or annual rebalancing. Your quarterly
statement will show activities to make tracking your investment easier.

DOLLAR COST AVERAGING

You can take advantage of a time-tested investment technique of dollar cost
averaging within your First Variable product. This strategy invests equal
amounts at regular intervals over time to take advantage of the natural ups and
downs of the financial markets. The key to dollar cost averaging is staying with
your plan, regardless of market performance. At First Variable, you can use
dollar cost averaging to move from one investment choice to another.

Dollar cost averaging does not assure a profit or protect against loss in
declining markets. Since prices fluctuate, consider your ability to continue
purchases through both high and low price levels.
